In the given figure,∆ABc is a right angled at B such that ∠BCA = 2∠BAC. Show that hypotenuse AC = 2BC

Answer»

$\bf\underline{\underline{\pink{Question:-}}}$

★In the given figure,∆ABc is a right angled at B such that ∠BCA = 2∠BAC. SHOW that hypotenuse AC = 2BC

$\bf\underline{\underline{\blue{Given:-}}}$

★A ∆ABC in which ∠B = 90° and ∠BCA = 2∠BAC

$\bf\underline{\underline{\red{To Prove:-}}}$

★AC = 2BC

$\bf\underline{\underline{\green{Construction:-}}}$

★Produce CB to D such that BD = BC. Join AD.

$\bf\underline{\underline{\orange{Proof:-}}}$

Let ∠BAC = x°. Then, ∠BCA = 2x°

In ∆ABC and ∆ABD, we have

BC = BD

AB = AB

∠ABC = ∠ABD

∴ ∆ABC ≅ ∆ABD

∴ ∠CAB = ∠DAB

and AC = AD

In ∆CAD, we have

∠CAD = ∠CAB + ∠DAB = (x° + x°) = 2x°

∠ACD = ∠ACB = 2x°

But, we know that the sides opposite to equal angles are equal.

∴ ∠ACD = ∠CAD => AD = CD

From (ii) and (iii), we GET

AC = CD => AC = 2BC [∵ CD = BC + BD = 2BC]

HENCE, AC = 2BC

17.	calculate angle AOC angle BOD and angle AOE in the adjoining figure it is being given that angle COD equal 90 degree angle BOE = 72 degree and angle AOB is a straight line
Answer» $\bf\underline{\underline{\pink{Question:-}}}$ ★Calculate ∠AOC, ∠BOD and ∠AOE in the adjoining figure, it is being given that ∠COD = 90°, ∠BOE = 72° and ∠AOB is a straight LINE. $\bf\underline{\underline{\blue{Solution:-}}}$ Since, AOB is a straight line the sum of all angles on the lower side of AOB at the point O on it, is 180°. ∴ ∠AOB + ∠BOE = 180° ==> 3x + 72° = 180° ==> 3x = (180° – 72°) ==> 3x = 108° ==> X = 108/3 ==> x = 36° Again, AOB is a straight line and O is a point on it. So, the sum of all angles on the upper side of AOB at a point O on it,is 180°. ∴ ∠AOC + ∠COD + ∠DOB = 180° ==> x + 90 + y = 180 [∵ ∠AOC = x°, ∠COD = 90° and ∠DOB = y°] ==> 36 + 90 + y = 180 [∵ x = 36°] ==> 126° + y° = 180° ==> y = 180 – 126 ==> y = 54° ∴ ∠AOC = x° = 36°, ∠BOD = y° = 54° ∠AOC = 3x = (36 × 3) = 108°

17.

calculate angle AOC angle BOD and angle AOE in the adjoining figure it is being given that angle COD equal 90 degree angle BOE = 72 degree and angle AOB is a straight line

Answer»

$\bf\underline{\underline{\pink{Question:-}}}$

★Calculate ∠AOC, ∠BOD and ∠AOE in the adjoining figure, it is being given that ∠COD = 90°, ∠BOE = 72° and ∠AOB is a straight LINE.

$\bf\underline{\underline{\blue{Solution:-}}}$

Since, AOB is a straight line the sum of all angles on the lower side of AOB at the point O on it, is 180°.

∴ ∠AOB + ∠BOE = 180°

==> 3x + 72° = 180°

==> 3x = (180° – 72°)

==> 3x = 108°

==> X = 108/3

==> x = 36°

Again, AOB is a straight line and O is a point on it.

So, the sum of all angles on the upper side of AOB at a point O on it,is 180°.

∴ ∠AOC + ∠COD + ∠DOB = 180°

==> x + 90 + y = 180 [∵ ∠AOC = x°, ∠COD = 90° and ∠DOB = y°]

==> 36 + 90 + y = 180 [∵ x = 36°]

==> 126° + y° = 180°

==> y = 180 – 126

==> y = 54°

∴ ∠AOC = x° = 36°, ∠BOD = y° = 54°

∠AOC = 3x = (36 × 3) = 108°

Three boys ANKUR, Brijesh and chitprag are sitting at equal distances on its boundary, each having a toy telephone in his hands to talk to each other. Find the LENGTH of the string of each phone. $\bf\underline{\underline{\green{Solution:-}}}$ Let A, B and C be the position of snkur, Brijesh and Chitprag respectively. Now, arc AB = arc BC = arc CA ==> chord AB = chord BC = chord CA ==>∆ABC is an equilateral triangle. Let AD, BE and CFcbe the MEDIANS of the ∆ABC and let G be it's centeroid. Since,in an equilateral triangle, the centeroid coincides with its circumcentre, we have GA = GB = GC = 20m Since the centeroid of a triangle devides a median in the ratio 2:1, we have GA\GD = 2\1 => 20m\GD = 2\1 => GD = 10m In right ∆BDG, we have BG² = BD² + GD² ==> (20m)² = BD² + (10m)² ==> 400m² = BD² + 100m² ==> BD² = (400 – 100)m² ==> BD² = 300m² ==> BD = √300 m ==> BD = 10√3 m ∴ BC = 2 × BD = (2 × 10√3)m = 20√3 m.

A circular park of radius 20m is situated in a calony. Three boys Ankur, Brijesh and chitprag are sitting at equal distances on its boundary, each having a toy telephone in his hands to talk to each other. Find the length of the string of each phone.

Answer»

$\bf\underline{\underline{\pink{Question:-}}}$

★A circular park of radius 20m is situated in a CALONY. Three boys ANKUR, Brijesh and chitprag are sitting at equal distances on its boundary, each having a toy telephone in his hands to talk to each other. Find the LENGTH of the string of each phone.

$\bf\underline{\underline{\green{Solution:-}}}$

Let A, B and C be the position of snkur, Brijesh and Chitprag respectively.

Now, arc AB = arc BC = arc CA

==> chord AB = chord BC = chord CA

==>∆ABC is an equilateral triangle.

Let AD, BE and CFcbe the MEDIANS of the ∆ABC and let G be it's centeroid.

Since,in an equilateral triangle, the centeroid coincides with its circumcentre, we have

GA = GB = GC = 20m

Since the centeroid of a triangle devides a median in the ratio 2:1, we have

GA\GD = 2\1 => 20m\GD = 2\1 => GD = 10m

In right ∆BDG, we have

BG² = BD² + GD²

==> (20m)² = BD² + (10m)²

==> 400m² = BD² + 100m²

==> BD² = (400 – 100)m²

==> BD² = 300m²

==> BD = √300 m

==> BD = 10√3 m

∴ BC = 2 × BD = (2 × 10√3)m = 20√3 m.

Hence, the length of each telephone string is 20√3 m.
